Warning on task property validation when building

[Chanseok Oh]

What's this? Should this be taken care of?

$ ./gradlew clean build
...
>  Task :validateTaskProperties
Task property validation finished with warnings:
  - Warning: Task type 'com.google.cloud.tools.gradle.appengine.appyaml.StageAppYamlTask': property 'stagingExtension.extraFilesDirectories' is not annotated with an input or output annotation.
  - Warning: Task type 'com.google.cloud.tools.gradle.appengine.standard.StageStandardTask': property 'stageStandardExtension.dockerfile' has @Input annotation used on property of type java.io.File.

Yeah, I think dockerfile needs to be updated to be @InputFile, however I'm not sure how to handle the extraFilesDirectories parameter, maybe there's a way to specify that it is handled by another method? I'll look around

I think we do something similar with Jib? Something like having two getters, one that returns a String and has the @Input annotation, and one that returns a Path (or File in this case) that has @Internal. Maybe adding @InputFile to the internal one would work?
